Prysmatic Labs Beacon Chain Implementation

This is the main project folder for the beacon chain implementation of Ethereum Serenity in Golang by Prysmatic Labs. Before you begin, check out our Contribution Guidelines and join our active chat room on Discord or Gitter below:

Also, read the latest sharding + casper design spec, this design spec serves as a source of truth for the beacon chain implementation we follow at prysmatic labs. Check out the FAQs. Refer this page on why we are combining sharding and casper together.
